onsemi NCV866710D150R2G

Overview

NCV866710D150R2G from onsemi is a high-accuracy, low-dropout linear voltage regulator optimized for automotive applications, delivering 150 mA output current with ±2% output voltage tolerance at 10 V, 45 μA quiescent current, and operation over −40 °C to +150 °C junction temperature. It serves as a primary power supply for engine control units (ECUs) and body control modules requiring stable bias under cold-crank conditions.

For engineers reviewing the NCV866710D150R2G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification, reverse-battery protection, thermal shutdown, and guaranteed performance across extended temperature and input voltage ranges (4.5 V to 45 V).

Technical Context

The NCV866710D150R2G integrates a precision bandgap reference, error amplifier, and PNP pass transistor in a single monolithic structure. Its internal architecture supports fixed 10 V output without external feedback components and includes built-in current limiting and thermal foldback to maintain safe operation during overload.

It features active reverse-battery protection down to −42 V, enabling direct battery connection in 12 V automotive systems. The device meets ISO 7637-2 pulse 5a (load dump) immunity up to 60 V with external clamp diode, and supports start-stop functionality via ultra-low quiescent current.

FAQ

What is the maximum input voltage rating for the NCV866710D150R2G?

The NCV866710D150R2G supports an absolute maximum input voltage of 45 V, making it compatible with standard 12 V automotive battery systems including load dump transients when used with appropriate external clamping. This rating is validated per ISO 7637-2 test conditions and reflects the device's design for under-hood deployment where voltage spikes are common. The NCV866710D150R2G maintains regulation down to 4.5 V input, covering cold-crank scenarios.

Does the NCV866710D150R2G require external capacitors for stability?

Yes, the NCV866710D150R2G requires a minimum 10 μF low-ESR ceramic output capacitor and a 1 μF ceramic input capacitor placed close to the IN and OUT pins. These capacitors ensure loop stability, transient response, and noise suppression. The NCV866710D150R2G is not unity-gain stable with smaller capacitance values, and omitting them may cause oscillation or poor line/load regulation. onsemi's datasheet specifies exact ESR and capacitance ranges for reliable operation.

Is the NCV866710D150R2G pin-compatible with other variants in the NCV8667 family?

No, the NCV866710D150R2G is not pin-compatible with other NCV8667 variants such as NCV866750D150R2G (5 V output) or NCV866733D150R2G (3.3 V output), despite sharing the same SOIC-8 package and pinout configuration. All variants use identical pin assignments (IN, GND, OUT, EN, SENSE, NC×2), but output voltage is laser-trimmed during manufacturing and cannot be altered externally. Therefore, substitution requires verification of voltage compatibility in the target circuit.

What protection features are integrated into the NCV866710D150R2G?

The NCV866710D150R2G integrates reverse-battery protection (−42 V), thermal shutdown with hysteresis (trip at 170 °C, release at 150 °C), and current limiting (typically 200 mA). It does not include overvoltage protection or watchdog functionality. These protections operate autonomously without external components, enhancing system robustness in automotive environments. The NCV866710D150R2G's enable pin also allows software-controlled shutdown to reduce leakage during deep sleep modes.

Can the NCV866710D150R2G be used in non-automotive applications?

Yes, the NCV866710D150R2G can be used in industrial or commercial applications requiring high-reliability 10 V regulation, especially where wide input range (4.5–45 V), low quiescent current (45 μA), or reverse-polarity resilience are beneficial. However, its AEC-Q100 qualification and automotive-focused testing make it over-specified-and potentially higher-cost-for non-automotive use. For such cases, non-automotive equivalents like the MC78L10ACDR2G may offer better cost/performance trade-offs unless the NCV866710D150R2G's specific features are required.
